摘要
介绍了最小二乘配置的基本原理和抗差协方差函数的拟合原理,给出抗差最小二乘配置的求解过程,并通过实例讨论抗差最小二乘配置在GPS高程拟合中的有效性和解决最小二乘配置不具有抗差性的不足。
The basic principles of the least squares collocation and fitting by robust covariance function are expounded, and the data processes of the robust solution of the least-squares collocation is given. Finally, we show the effectiveness of the robust least-square collocation by a real example of the GPS elevation fitting.
